Our venerable and God-bearing Father Nicodemus of the Holy Mountain (or Nikodemos the Hagiorite) was a great theologian and teacher of the Orthodox Church, reviver of hesychasm, canonist, hagiologist, and writer of liturgical poetry.

St. Nicodemus was born c. 1749 in Naxos, Greece. In 1775 he became a monk at Mount Athos. He worked with Saint Macarius Notaras of Corinth to compile the Philokalia, a defining work on monastic spirituality. He edited and reworked two books on Western spirituality which had already been translated into Greek and wrote many original works including Lives of the Saints.

St. Nicodemus reposed in the Lord in 1809 and was glorified by the Orthodox Church in 1955. His feast day is celebrated on July 14.
